Remember, You Have Complete Source Code. "AudioInputDevice" is an abstract base class, implemented by a subclass. You are (I presume) using the "WindowsAudioInputDevice" subclass, whose source code is in the "WindowsAudioInputDevice" directory (and has two possible implementations - one that uses Windows' built-in software 'mixer', and one that doesn't). You can review that code to figure out how it works. If you are not happy with either of the current implementations, then you can - if you wish - provide your own. This would be another subclass of "AudioInputDevice" (ideally with a different name than "WindowsAudioInputDevice", to avoid confusion). You would reimplement the "AudioInputDevice::createNew()" function to create an instance of your new subclass, rather than "WindowsAudioInputDevice".
